I have three pcs connected as a peer to peer network. I wanted to setup a mail server in order to be able to send emails into my lan. I'm not interested in sending emails outside of my lan with this server.
I set up hmailserver (HMS), I created a visual domain (mydomain.com) and three users like firstname.lastname@example.org. On pc1 where I installed HMS everything works fine. Both Outlook express and HMS work with no problem (diagnostic's tools results are all green). The problem is with the other pcs. When I try to send or receive an email from pc2 or pc3 I get a time out error. I set the local ip of pc1 (192.168.2.2) as the pop and smtp address. I tried to use 587 port but with no result. When I give the command telnet 192.168.2.2 25 from pc2 I get a connection error but when I set smtp port to 587 in HMS and give the command telnet 192.168.2.2 587 I get a connection (220 mail.mydomain.com) but in outlook express I still get the same error.
Before HMS I used mercury/32 mail server and everything worked fine, with the same settings (firewall, ports) !
I don't know what else can I do!
